John “Junior” Gotti tried out a new role yesterday – that of a victim – as he accused the feds of pursuing a vendetta that could get him killed.

“If I get one in the head, does that make it all better?” the former Gambino crime-family godfather said in the wake of a report that investigators are seeking to pin charges on him for at least five murders, narcotics trafficking and paying off crooked cops.

“My family lives in fear as a result of this,” Gotti said a day after The Post reported details of the probe.

The mob scion lashed out as he left federal court in White Plains, where prosecutors accused him of hiding assets and stiffing Uncle Sam out of $200,000 in taxes – offenses that could land him behind bars for violating his probation.

Assistant US Attorney David Massey is seeking full access to Gotti’s financial records and told Judge Stephen Robinson that “if we would look at these documents, in a very short time I honestly believe we would find false statements.”

Gotti was ordered to fork over back taxes as a condition of a 1999 guilty plea in which he admitted to trying to shake down the Manhattan strip club Scores and was sentenced to more than six years in prison and a term of probation.

“I understand there’s a history with Mr. Gotti. I understand the government doesn’t fully trust Mr. Gotti,” Robinson said, but stopped short of ordering Gotti to disclose his financial records and instructed both sides to put their arguments in writing.

Calling Gotti “a moving target with regard to his financial records,” Robinson said, “It is fair for the Probation Department to say, ‘We need to figure out what really is going on.’ ”

Gotti is under investigation for his alleged role in five murders, including the 1983 slaying of 24-year-old Danny Silva during a barroom brawl, sources said. Mob turncoats have told the feds the crime family paid off a number of renegade cops to cover up the crimes.

Gotti’s new legal woes follow close on the heels of three mistrials in Manhattan federal court, where he was accused of extortion, witness tampering and the sensational 1992 kidnapping of radio host Curtis Sliwa, among other crimes.

Defense lawyer Charles Carnesi accused the feds of pursuing Gotti because of his family name.

“The stark reality of it is Mr. Gotti is always a target of the government,” said Carnesi, denying that his client owes the government money. “His IRS obligation is over,” Carnesi said. “During the last three trials the great portion of the evidence involved was his financial records . . . they’ve combed them back and forth.”
